Our investigation has shown that:ⅰ there was an interference effect between the incident and reflected matter waves as all the atoms in BECs were coherent;ⅱ considering the rotation of a vortex, the nonuniform velocity distribution along the surface would play an important role in the quantum reflection process. For example, they would change the characteristics of the interference fringes between the incident and reflected matter waves;ⅲ the reflected vortex became unstable for sufficiently low incident velocity or strong interaction. This sort of instability physically originated from dynamics excitations induced by the atomic interaction in the quantum reflection process.

我們的研究表明：ⅰ由于相干性質(zhì)的存在800级毛片，在渦旋與固體表面相互作用的過程中，被固體表面反射回去的部分與正在入射的部分在空間疊加后一定會產(chǎn)生清晰的干涉條紋亚洲欧美日韩精品一区；ⅱ由于各向異性的速度分布日本在线视频中文字幕，渦旋的反射率也呈各向異性，因此反射回來的部分與入射部分形成的干涉條紋寬度以及疏密程度與入射速度以及速度各向異性的程度有關(guān)禁止18岁以下观看,黄片；ⅲ由于玻色凝聚體中原子間相互作用的存在三级国产精品，反射過程中凝聚體會產(chǎn)生激發(fā)，破壞渦旋的結(jié)構(gòu)偷拍照片网，使得反射后的渦旋不再是中心對稱男人插女人逼逼的视频。

Templating agent could not be sufficiently removed at temperature below 500℃, while temperature exceeding 600℃ might result in collapse of the framework. The conversion from Co(superscript 2+) to Co(superscript 2+) was a gradual time-consuming process. Calcination at 550℃ in a muffle furnace for 10 hours could remove the templating agent and bond water and give a satisfactory result.
